errno should be thread local. man errno on Linux, for example, says:

       errno  is defined by the ISO C standard to be a modifiable
       lvalue of type int, and must not be  explicitly  declared;
       errno  may  be a macro.  errno is thread-local; setting it
       in one thread does not  affect  its  value  in  any  other
       thread.

Cheers,

Duncan.
